The knowledge of directions of arrival (DOA) of waves is fundamental in understanding the physics of the mobile communications wide-band propagation channel. We first present a measurement setup that is able to accurately measure these DOA. It is bas

TROPICS is a rule-based scheduling system that optimizes the training experience for students in a power (note this change should be everywhere, i.e. Not reactor) plant environment. The problem is complicated by the condition that plant resources and

A statistical representation model of the wideband radio propagation channel is proposed. This model is intended to be used in a software channel simulator. This approach is original with regard to more classical ray models because it does not try to

We propose a new model for the mobile radio channel which takes into account the channel non-stationarity. It is a statistical model whose parameters are derived from real impulse responses. It is based on modelling the variations of an existing stat

A computer code based on digitized terrain data was developed to estimate path losses and selectivity characteristics of the urban radio channel between a mobile located in a street and a base station on the roof of a high building. The principle of

Channel sounding experimental equipment to measure the wideband and variability characteristics of the 900 MHz mobile radio channel is presented. This equipment uses a modulated carrier, but no analog correlator. Various sources of nonlinearities may

The wish to develop in the future the Universal Mobile Telephone System (UMTS) with an indoor radio coverage makes it necessary to characterise this propagation environment. For this purpose, a channel sounder matched to this environment has been dev

Future third generation cellular systems (UMTS in Europe, IMT-2000 for ITU) will offer an increased range of services, and thus should accommodate much higher service bit rate than second generation. Unless the use of these new services is limited to
